Treasury yields climbed steadily throughout the week, pushing the 10-year yield above 4.60 percent and lifting shorter maturities to their highest levels since early 2025, while the 30-year Treasury yield remained above 5 percent for its longest stretch since 2007. Investors are increasingly demanding greater compensation for holding long-dated government debt as concerns over persistent inflation, expanding fiscal deficits, and a Treasury market nearly six times larger than before the Global Financial Crisis outweigh the fact that the Federal Reserve’s policy rate remains well below prior tightening cycles. A weak 20-year Treasury auction, robust global equity markets, and rising energy prices reinforced defensiveness, leaving bond markets vulnerable to further weakness (should key technical resistance levels give way).
Although recent inflation data suggest underlying price pressures are gradually moderating, markets (and Fed voters) remain skeptical that a single benign inflation report is sufficient to declare victory over inflation, particularly as higher energy prices threaten to spill over into broader inflation expectations. The Fed is widely expected to leave rates unchanged at next week’s meeting, but investors continue to assign meaningful odds to a September rate hike as Chair Warsh maintains a hawkish posture and policymakers await further inflation data. New tariff announcements targeting major U.S. trading partners generated relatively little reaction in Treasury markets, showing that geopolitical developments and energy prices remain the dominant drivers of investor sentiment during the Fed’s communications blackout period and a seasonally light economic calendar.
Freddie Mac reported that the average 30-year fixed mortgage rate climbed for a third consecutive week to 6.58 percent, while mortgage applications from MBA rose 1.9 percent, driven by a surprisingly resilient 6 percent increase in purchase activity despite financing costs reaching their highest levels in nearly a year. Even so, higher mortgage rates remain a meaningful headwind for both affordability and housing demand. Agency mortgage production has recovered significantly from the refinancing drought that followed the Federal Reserve’s post-pandemic tightening campaign, with first-half 2026 Agency MBS issuance rising 28 percent year over year as refinancing activity rebounded. However, higher rates following the U.S.-Iran conflict are expected to slow prepayments and moderate issuance in coming months, although today’s market differs materially from 2023 because a meaningful share of homeowners still retains refinance incentive. Industry estimates suggest every 25-basis-point increase in mortgage rates reduces monthly mortgage production by roughly $10 billion. Both purchase and refinance activity remain highly sensitive to further increases in borrowing costs.
Agency mortgage-backed securities continued to modestly underperform despite relatively stable interest-rate volatility. Unlike traditional bonds, MBS contain embedded homeowner prepayment options that create nonlinear price and duration behavior as interest rates change. Today’s elevated mortgage rates have pushed many legacy low-coupon securities far out of the money, significantly reducing the sector’s traditional negative convexity and creating a more stable hedging environment. Nevertheless, higher-coupon securities continue to exhibit meaningful extension and prepayment risk, making collateral composition increasingly important, particularly for pools containing loans with note rates near prevailing mortgage rates. Relative valuations also remain supportive, with Agency MBS appearing modestly cheap compared with both Treasuries and investment-grade corporates, while Fannie Mae 15- and 20-year securities and select newer-vintage specified pools continue to offer attractive value opportunities.
Outside the capital markets, industry activity saw consolidation continue as larger firms expanded scale through acquisitions and strategic financing initiatives, highlighted by Union Home’s acquisition of AmeriTrust and Rocket’s multibillion-dollar credit agreement with JPMorganChase, while NEXA Lending resolved long-running litigation that leaves CEO Mike Kortas as the company’s sole owner. Overall, this week’s developments reminded us that while housing finance activity has stabilized well above the cycle lows of recent years, persistent inflation concerns, elevated interest rates, and geopolitical uncertainty continue to define things.
